Description of a Mainframe Computer

Today’s mainframes are different from earlier mainframe computers because the latest versions are performing far better than the previous versions. Developers are still working on mainframes to invent better versions. All these versions are capable of offering features like reliability, security and compatibility

Mainframes are large computers designed for handling/processing large amount of business data at higher speed without any interference. Once installed, these machines operate for several years. Mainframes operate with different operating systems at a faster rate consuming high power of electricity and requires cooling devices to keep systems cool as it generates heat. Mainframes also serve multiple users in an efficient way by processing transactions in a batch form.

Mainframes’ operating systems are different from the servers operating systems. Mainframes have the capability of processing billions of instructions per second producing precise results. Mainframes’ OS looks like single operating system is running, but behind multiple processors are running.

The earlier versions of mainframe computers were very large compared to regular PCs and occupied 10 to 12 square feet of room space, but modern mainframes are available in smaller sizes and are giving more computing results than the previous versions.
